In einer Weiterbildung der Erfindung weist die Autobetonpumpe einen elektrischen Energiespeicher, insbesondere einen Akkumulator, auf. Der elektrische Energiespeicher ist, insbesondere durch beziehungsweise über einen, insbesondere den und/oder elektrischen, Konverter beziehungsweise Umsetzer, mit dem flüssigkeitsgekühlten Synchronantriebsmotor elektrisch verbunden. Des Weiteren ist der elektrische Energiespeicher zur Abgabe elektrischer Leistung beziehungsweise elektrischer Energie an den flüssigkeitsgekühlten Synchronantriebsmotor ausgebildet. Dies ermöglicht die Autobetonpumpe bei Nicht- Vorhandensein eines elektrischen Baustellennetzanschlusses mindestens teilweise elektrisch zu betreiben. Wird mehr Leistung benötigt, kann das Verbrennungsantriebsmotorsystem zugeschaltet werden. Insbesondere kann die Autobetonpumpe dazu ausgebildet sein, den elektrischen Energiespeicher durch beziehungsweise über den flüssigkeitsgekühlten Synchronantriebsmotor als Generator von dem Verbrennungsantriebsmotorsystem aufzuladen, insbesondere falls das Verbrennungsantriebsmotorsystem mehr Leistung beziehungsweise Energie liefern kann, als von dem Hydraulikantriebspumpsystem, insbesondere temporär, benötigt. In a further development of the invention, the truck-mounted concrete pump has an electrical energy store, in particular an accumulator. The electrical energy store is electrically connected to the liquid-cooled synchronous drive motor, in particular by or via a, in particular the and / or electrical, converter or converter. Furthermore, the electrical energy storage device for the discharge of electrical Power or electrical energy trained on the liquid-cooled synchronous drive motor. This enables the truck-mounted concrete pump to be operated at least partially electrically in the absence of an electrical construction site network connection. If more power is required, the internal combustion engine system can be switched on. In particular, the truck-mounted concrete pump can be designed to charge the electrical energy store through or via the liquid-cooled synchronous drive motor as a generator from the internal combustion engine system, in particular if the internal combustion engine system can deliver more power or energy than is required, in particular temporarily, by the hydraulic drive pump system.
In einer Ausgestaltung der Erfindung ist der elektrische Energiespeicher zur Aufnahme von dem flüssigkeitsgekühlten Synchronantriebsmotor, insbesondere temporär beziehungsweise zu einem ersten Zeitpunkt, nicht benötigter beziehungsweise überschüssiger elektrischer Leistung von beziehungsweise mit dem Elektrizitätsnetzanschluss, insbesondere durch beziehungsweise über einen, insbesondere den und/oder elektrischen, Konverter beziehungsweise Umsetzer, elektrisch verbunden und ausgebildet. Des Weiteren ist der elektrische Energiespeicher zur Abgabe von dem flüssigkeitsgekühlten Synchronantriebsmotor, insbesondere temporär beziehungsweise zu einem von dem ersten verschiedenen, zweiten Zeitpunkt, benötigter elektrischer Leistung beziehungsweise elektrischer Energie zusätzlich zur elektrischen Leistung von dem Elektrizitätsnetzanschluss ausgebildet. Typischerweise stellt der elektrische Baustellennetzanschluss nur eine begrenzte elektrische Leistung bereit beziehungsweise ist auf eine bestimmte elektrische Leistungsbelastung begrenzt. Die Autobetonpumpe, insbesondere der elektrische Energiespeicher, ermöglicht, dass dem flüssigkeitsgekühlten Synchronantriebsmotor mindestens temporär beziehungsweise zeitweise mehr elektrische Leistung zur Verfügung steht als von dem elektrischen Baustellennetzanschluss bereitgestellt. Insbesondere können einen, insbesondere kurzzeitigen, relativ hohen Leistungsbedarf beziehungsweise eine Leistungsspitze des flüssigkeitsgekühlten Synchronantriebsmotors der Elektrizitätsnetzanschluss beziehungsweise der elektrische Baustellennetzanschluss und zusätzlich der elektrische Energiespeicher decken, insbesondere gleichzeitig. Zu Zeitpunkten mit relativ geringem Leistungsbedarf kann der elektrische Energiespeicher die nicht benötigte elektrische Leistung des Elektrizitätsnetzanschlusses aufnehmen. In anderen Worten: bei Überlast kann der elektrische Energiespeicher angezapft werden, bei Leistungsreserve kann der elektrische Energiespeicher aufgeladen werden. In one embodiment of the invention, the electrical energy store for receiving the liquid-cooled synchronous drive motor, in particular temporarily or at a first point in time, is unnecessary or excess electrical power from or with the electricity network connection, in particular through or via a converter, in particular the and / or electrical converter or converter, electrically connected and trained. Furthermore, the electrical energy store is designed to emit the liquid-cooled synchronous drive motor, in particular temporarily or at an electrical power or electrical energy required in addition to the first different second time, in addition to the electrical power from the electricity network connection. The electrical construction site network connection typically only provides a limited electrical power or is limited to a specific electrical power load. The truck-mounted concrete pump, in particular the electrical energy store, enables the liquid-cooled synchronous drive motor to have at least temporarily or temporarily more electrical power than is provided by the electrical construction site network connection. In particular, a, in particular short-term, relatively high power requirement or a power peak of the liquid-cooled synchronous drive motor can cover the electricity network connection or the electrical construction site network connection and additionally the electrical energy store, in particular simultaneously. At times with a relatively low power requirement, the electrical energy store can absorb the electrical power of the electricity network connection that is not required. In other words, the electrical energy store can be tapped in the event of an overload, and the electrical energy store can be charged when there is a power reserve.
